Just got my hands on an N950. The SIM card slot is full size (or mini, the full, credit card size cards are obviously not used). The bottom right hand side "slot" is the audio speaker AFAIK. So there's only mono, no stereo as on the N900. I'm going to play around with it now, so just ask if you are curious about anything and I'll try to answer as good as I can. But I can't promise I have the answer to all details just because I have the device here And I'm not working for Nokia, so I have no knowledge of internal details. What I can tell you from the first minutes of experience is that everything synced fine over bluetooth with the N8 (which again was synced with the N900), except the calendar. N950 is longer than the N900, and a bit wider, but thinner. It's about as thick as the N900's body without the screen. Compared to the N8 it is almost the same size, but a bit longer. It's all extra screen real estate, so I'm happy about that The screen is not convex as on the N9, but the swipe from the edge still works good.
